Rudolf made a big splash when his first single, "Let It Rock," became a national sensation, reached No. 1 and was adopted by countless TV shows and even the Philadelphia Phillies amid their 2008 World Series run. The subsequent debut album features twelve rock-tinged/hip-hop-flavored pop songs founded on Rudolf's semi-dangerous guitars and well-treated singing voice, as well as high profile rapper cameos by Nas, Lil Wayne and Rick Ross. "Welcome to the World" turns the trick of beating out the rest of the album for catchiest song, while "Coffee and Donuts" mellows out Shakira's "Objection."
